  • Patent number: 9057355
    Abstract: Disclosed is a wind turbine with a generator, which minimizes design limitations on the diameters of generators and allows a rotor and the generator to be stably fixed to a tower. The wind turbine includes a rotor including a hub at a center thereof, a rotating shaft protruding rearward of the hub, and a plurality of rotor blades provided around the hub; a generator including a housing disposed at an outer upper portion of a tower behind the rotor and provided at an inner surface of a cylindrical body thereof with a stator and a rotator rotatably coupled in the housing to rotate together with the rotor; and a support bracket fixed to an upper end portion of the tower, wherein the housing is fixed to a front surface of the support bracket to integrally fix the rotor and the generator to the tower.

  • Publication number: 20100219642
    Abstract: Disclosed is a wind turbine comprising a nacelle frame provided with one main bearing on the front surface thereof; a rotor including a rotor hub provided with a hollow drum shaft, installed on the inner ring of the main bearing, at the rear thereof; an acceleration gear box including an input shaft, connected to the tip of the hollow drum shaft, at the front portion thereof and an output shaft at the rear portion thereof, and floating in the nacelle frame under the condition that the acceleration gear box is separated from the nacelle frame for increasing the rotational speed of the input shaft and transmitting the rotation of the input shaft to the output shaft; a torque supporter installed between the acceleration gear box and the nacelle frame for preventing the acceleration gear box from self-rotating; and a generator including a rotary shaft connected to the output shaft.

  • Patent number: 7642668
    Abstract: Disclosed is a power transmission apparatus for a wind generator having an electric generator connected to an apparatus rotor by a main shaft. The electric generator includes a generator rotor and a generator stator. The electric generator may be assembled to the main shaft via the generator rotor, but the generator stator is not assembled to the main shaft. Instead, the generator stator is connected to a stator housing fixed to bearing housings respectively provided on a pair of bearings disposed on an outer surface of a rotor bearing. The rotor bearing is disposed perpendicular to a vertical rotor frame, is formed integrally with the generator rotor, and is connected to an outer surface of the main shaft. The apparatus permits the generator stator to be assembled with a circumference of the generator rotor. The apparatus provides increased convenience and efficiency in assembly.

  • Publication number: 20090250935
    Abstract: Disclosed is a rotor for a wind turbine, which prevents permanent magnets from being separated from the rotor due to the melting of portions of the permanent magnets bonded to the rotor by a high temperature atmosphere without burying the permanent magnets in the rotor. The rotor includes a circular body provided with grooves having a trapezoidal shape, horizontally formed in the outer circumferential surface of the circular body, and spaced at regular intervals, the central portion of the circular body being connected to a rotary shaft; permanent magnets having a trapezoidal shape and detachably inserted horizontally into the grooves; and fixing rings detachably installed respectively on the front and rear surfaces of the circular body so as to be closely attached to the front and rear surfaces of the permanent magnets to fix the permanent magnets.

  • Publication number: 20080272602
    Abstract: Disclosed is a wind turbine, in which the assembly of a rotor and a stator of a generator with a main shaft connecting a turbine rotor and the generator is completed only by assembling the rotor of the generator with the main shaft without assembling the stator of the generator with the main shaft. In the wind turbine, a rotor bearing being perpendicular to a vertical rotor frame is formed integrally with the rotor of the generator and is connected to the outer surface of the main shaft, a pair of electric bearings is disposed at the outer surface of the rotor bearing, and the stator of the generator is assembled with the rotor of the generator by fixing a stator housing to bearing housings of the electric bearings. Thereby, convenience and efficiency in assembly are increased.
